SPINNING, TWISTING, AND LIKE FRAME.

Application filed September 4, 1925, Serial No.

This invention relates to flyer spinning and like frames and has for its primary object to obtain greater regularity of drag on the thread being spun, whereby spinning may be effected in less time and with a greater degree of perfection than heretofore. A secondary objectis to provide a construction in which the spindle is readily disengageable from its driver.

In frames to which the invention is-applicable the flyers are mounted on an upper rail with their legs extending downwards while the spindles are mounted coaxially therewith "in a lower position. Characteristic of the invention is the feature that each spindle is driven otherwise than by contact with the bobbin or the like which is being spun and is traversed with its bobbin in relation to the flyer, or the flyer may be traversed in relation to the spindle. v

In the accompanying drawings Figs. 1 and 2 are elevations of flyers arranged to drive spindles. Figs. 3 and d are details of Figs. 1 and 2 to a larger scale. Figs. 5 and 6 show a telescopic spindle driven by a flyer. F ig. 7 shows a spindle driving a flyer.

Referring to Fig. 1, 1 denotes a top spindle rail which in practice extends along one side of the frame. Mounted in said rail 1 in a bearing 2 is a flyer 3 rotatable about a vertical axis and having a wharve 3 The yarn 4c to be spun passes through the flyer boss to the curl 3 at the lower end of one of the depending legs of the flyer 3 and thence to the bobbin 5. The flyer 3 is driven in usual manner by a tape 6 wrapping the wharve 3 At a suitable distance below the flyer 3 there is mounted on traverse slides 7 a lifting rail 8 adapted to be traversed up and down in usual manner. The lifting rail 8 is hori- Zontal and parallel with the top spindle rail 1 and extends along the same side of the frame. Coaxial with the flyer 3 a hole is formed in the lifting rail 8 and in the hole is mounted an upwardly extending stud 9. The stud has a collar 9 (Fig. 3) resting on the top of the lifting rail 8 and is bound by a nut 9 on the under side of the rail 8. On the stud 9 is mounted a hollow bobbin carrier 10. The bobbin carrier 10 is bored upwards from its'lower' end to a suitable distance, and, when impaled on the stud 9, works on the upper end of the latter. At the lower end of the bobbin carrier 10 is a flange 10 just clear of the collar 9 54,440, and in Great Britain December 5, 1924.

on the stud 9. Between the collar 9 and the I flange 10 is interposed a loose washer. 'On the collar .9 of the stud 9 is screwed a drag collar 11 extending slightly above the flange 10 The collar 11 has at the upper end an inturned rim 11 which prevents the bobbin carrier 10 from being lifted off the stud 9. On the bobbin carrier 10 is mounted the spinning bobbin 5. The upper end of the bobbin carrier 10 extends above the bobbin '5 far enough to receive a jointed driver 12 which is held vertical or horizontal by means of a plunger 13 and spring 14 received in the upper end of the hollow bobbin carrier 10. The driver 12 is adapted to fold to a horizontal position and is long enough to engage with the legs of the flyer 3 by means of which the bobbin carrier 10 is driven. It will thus be understood that as the yarn 4 passes from the flyer 3 to the spinning bobbin 5 the flyer 3 at the same time rotates the bobbin carrier 10 on which the bobbin 5 is mounted, giving the same working effect as if the bobbin were carried on a spindle attached to a flyer.

In a second embodiment (Figs. 2 and 4c) in lieu of a stud and hollow bobbin carrier we employ a spindle 15 which we mount in a socket 16 in the lifting rail 8. The bobbin 5 is fitted upon the spindle 15 and sits on the lifting rail 8. To the upper end of the spindle 15 is jointed a driver 12 which engages with one of the flyer legs and by means of which the spindle 15 is driven. The driver 12 is foldable as described with reference to the first embodiment.

In a third embodiment (Figs. 5 and 6) 17 denotes a driven flyer on which is fixed a depending spindle 17 of polygonal section. The bobbin spindle 18 is formed with a bore 18 of polygonal section to receive "the spindle 17 whereby the bobbin spindle 18 is driven. The bobbin spindle 18 is mounted in a socket 16 on the lifting rail 8. When dofiing is to take place, the bobbin spindle 18 is lowered until it is clear of the flyer spindle 17 In cases in which the bobbin spindle is driven and drives the flyer, as shown in Fig. 7, a'fiyer 27 with depending legs 27 is mounted in bearings in a top rail 26. Coaxial with flyer 27 is mounted a spindle 28 carrying a wharve 29 wrap ed by a driving cord led from a usual tin ro ler serving a group of such spindles. The

spindle 28 is mounted in a rail 30 having one bearing 31 above the wharve 29 and a footstep 32 below the wharve. The rail 30 and the spindle 29 are adapted to be traversed up and operation. To the upper end of the spindle 28 is jointed a driver 33 foldable to horizontal position to engage and drive the fiyer 27. The spindle rail 30 and flyer 27 are lowered or tilted to dofi' the bobbin when filled.

What we claim is 1. In a flyer spinning Or like frame, in combination, a rotatable bobbin, a rotatable bobbin carrier to support said'bobbin laterally, said carrier supported entirely independently of said bobbin and having no driving connection with said bobbin, a fiyer mounted separately from said carrier, means independent of said bobbin for, transmitting rotation positively to said carrier and means for efiecting traverse of said carrier and bobbin relatively to said flyer without longitudinal movement of said bobbin relatively to said carrier.

2. In a flyer spinning or like frame, in

combination, a rotatable bobbin, a rotatable bobbin carrier supported entirely independently of said bobbin and having no drivdown during the spinning ing connection with said bobbin, a flyer supported independently of and coaxially with said carrier, a rotation-transmission element hinged to said carrier, said element adapted to effect a driving connection between said carrier and said fiyer, and means for effecting relative traverse of said carrier and said fiyer. I

3. In a flyer spinning or like frame, in combination, a bobbin, a rotatable bobbin carrier supported entirely independently of said bobbin, a rotatable flyer having depend ing legs and supported independently of and coaXially with said carrier, a rotationtra-nsmitting element adapted in oneposition to establish a driving connection between said carrier and said flyer, said'element being movable into position to disestablish said driving connection, a wharve rotation of which effects rotation of both said carrier and said flyer, and means for effectingrelative traverse of said carrier and said flyer.

In testimony whereof we have signed our names to this specification.
